10-24 Vehicle Care
12-Volt Battery
The 12-volt battery is in the trunk,
under the center compartment
cover. Refer to the replacement
number shown on the original
battery label when a new 12-volt
battery is needed. The vehicle has
an Absorbed Glass Mat (AGM)
12-volt battery. Installation of a
standard 12-volt battery will result in
reduced 12-volt battery life.
When using a 12-volt battery
charger on the 12-volt AGM battery,
some chargers have an AGM
battery setting on the charger.
If available, use the AGM setting on
the charger, to limit charge voltage
to 14.8 volts. Follow the charger
manufacturer's instructions.
Warning
Battery posts, terminals, and
related accessories contain lead
and lead compounds, chemicals
known to the State of California to
cause cancer and reproductive
harm. Wash hands after handling.

12 volt batteries have acid that
